Addicore Joystick with Push Button

Here is a nice little joystick from Addicore with push button action.  It's easy to use on the MSP430F5529LP.  It uses dual potentiometers for the x and y axis.  Note that there is a commented out line that you can use if desired to change the numeric value for the y axis so that zero voltage is down instead of up.  The x axis goes from zero at left to 4095 at right.  The F5529 has analog resolution of 4096 - you will need to change this to 1023 for Arduino or lower resolution MSP430s.

The Energia sketch below demonstrates how it works.
